everything about energy production
Hydro isn't only a source of energy, it's also the most efficient way to store energy. With solar and wind, peak usage hours don't match peak production hours, so we need storage capacity to be even able to use solar & wind. And dams are the absolute best we have for that storage purpose, in terms of cost, efficiency, and environmental impact
I think the best aspect about these dams is that they are already there. We don't need to do massive investments in our infrastructure to built giant batteries, since water power is already there and can be easily modified to act as storage additionally.
I agree it provides a more regular "stream" of energy. I think perhaps this focus on having regular unlimited energy at all times of night and day is a little unnecessary. People do sleep, and they should sleep during the night for maximum health, based on research. I find energy storage an important aspect of sustainability. We should have storage regardless of the system. I'm not against using it, all I said was it's not my favorite.
